In my first post, I referenced the fact that, while the six disc/subwoofer/nine speaker Soundmark unit in my car did a good job of providing music, it doesn't have the modern USB or aux inputs on the unit. No Bluetooth, either. With this in mind, I may have to give up the factory look to get these features. Youngoldman provided a picture of his Pioneer unit and it looks good. What is stopping me is, when I searched on the Crutchfield site, they mention that I would need to run new wiring to all the speakers. Something about the amp being in the trunk? I'm trying to understand the logic behind this, because the idea of a big rewiring job, especially to each door, doesn't necessarily appeal to me at this point. And I hope to avoid a major hack job on the existing wiring. I've done radio replacement before and it's not that difficult, but replacing existing wiring with new speaker wiring has me scratching my head. Advice from anyone who has tackled this same radio setup would be greatly appreciated, of course.
